[SCSI] Add spi_populate_*_msg functions
Introduce new helpers: - spi_populate_width_msg() - spi_populate_sync_msg() - spi_populate_ppr_msg() and use them in drivers which already enable the SPI transport. Signed-off-by: Matthew Wilcox <matthew@wil.cx> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
